ATTACHMENT FOR WOOL-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 653,836, dated July 17,1900.

Application filed October 10, 1899. Serial No. 733,126. (N model-l T0(tZZ whom it may concern.-

Be it known that I, AMARIAH AVERY, a citizen of the United States,residing at Man'- chester, in the county of Hillsborough and State ofNew Hampshire, have invented certain new and useful Improvements inAttachments for VVool-Spinning Frames; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates more especially to wool-spinning, but it isequally as well adapted to cotton-spinning, the objects being to windmore yarn or thread on a bobbin, to twist the fibers of the yarn moreuniformly than can be done by the use of the ordinary caps used inspinning wool, to obtain a more even tension, thus making the yarn moreeven and smooth, and, finally, to lessen the vibration of the spindles.The frequent stopping to doff consumes much time which by the use of myimprovements is saved, the bobbins being wound very evenly and much moretightly, thereby increasing the quantity of yarn on a bobbin betweenthree and four hundred per cent. over that which can be wound upon thesame when the cap is used. The invention consists in the constructionwhich will be fully set forth in the following specification and claimsand clearly illustrated in the drawings accompanying and forming a partof the same, of which- Figure 1 is a broken elevation showing a portionof a wool-spinning frame, several spindles and bobbins thereon, and myimproved stationary ring-rail and its rings in proper relation thereto.Fig. 2 is a plan view of the same parts. Fig. 3 is an enlarged detailplan view showing a portion of the stationary ring-rail and showing onemethod of attaching the rings thereto. Fig. 4 is a cross section of thestationary ring-rail having a ring attached. Fig. 5 is a detail inperspective showing a flanged block forming a portion of my improvedmethod for adjustably connecting the rings to the stationary ringrail.Fig. 6 is a detail plan view of an arm to which a ring may be'attachedand by which said ring may be connected to the stationary ring-rail.

Similar reference-letters designate corresponding parts in all theviews.

A represents one of the end, and A one of the horizontal end, connectingportions of an ordinary wool or cap spinning frame, said part A beingperforated for the reception of the vertically-movable spindles B.

O is a bar to which the spindles B are connected and upon Which aremounted flanged pulleys D, which carry the bobbins E, said bobbins beingdriven by the belts d, which connect a pair of the pulleys D with asuitable driving-pulley, (not shown,) and 0 represents one of the usualcam-operated rods attached to said bar 0, causing said bar and thebobbins thereon to rise and fall as required.

F represents the rings, which may be each secured to an arm G, and forthe purpose of adjusting said rings either to the right or left, so thatthey shall be concentric with the spindles, I provide the intermediateflanged plate H, resting between said arm G and a stationary ring-railI, to which said arm and plate may be secured in the following manner:The arm G is provided with an elongated opening g for the passage of aclamping-bolt, and so, also, is the stationary ringrail I provided withelongated openings 2', while the plate h has a central perforation h,and a suitable bolt J is provided whose func* tion is to clamp the arm Gand plate H to said stationary ring-rail I in whatever position desired.The said plate H is also pro vided with flanges 7t on two oppositesides, between which rests the arm G, and with flanges 71 on its othertwo sides and projecting in the opposite direction to those made toreceive the arm G, said flanges if being adapted to close over the edgesof the stationary ring-rail. Thus it will be seen that to adjust a ringF sidewise the flanged plate H must be moved upon the ring-rail I and toadjust a ring forward or backward the arm G must be moved upon the plateH, af-- ter which the bolt J may be tightened to readily maintain theproper adjustment of the said arm G and plate 1-1, the movement of theseparts being made possible by reason of the bolt J passing through theelongated openings g 2', respectively, of the arm G and ring-rail I andthrough the larger central perforation 7L in the plate H.

It is obvious that the ordinary ring-rail used in cotton-spinningframes, if made stationary, will serve a very good purpose in carryingmy invention into practice; but after many experiments I am of theopinion that to place the stationary ring-rail back of the spindles,attaching the rings thereto in the manner herein shown and described, ispreferable.

Chief among the advantages gained by the adoption of rings insubstitution for the caps in Wool-spinning is that the spindles can berun at much higher speed, thus winding the bobbins tighter, which meansmore yarn on a bobbin, with fewer knots, and the advantage of astationary ring-rail over a movable one is that the length of yarnbetween the rolls and the traveler on the ring is substantially uniformat all times, thus decreasing the liability of its breaking.

Having described my invention, what I claim is 1. In a spinning-machine,the combination upturned flanges on two opposite sides of the blockstanding astridethe arm, as and for the purpose set forth.

2. In a spinning-machine, the combination with a series of spindles, anda ring-rail adjacent to and parallel with said series, the rail havingopenings opposite the spindles elongated in the direction of its length;of a ring for each spindle, an arm supporting each ring and resting uponthe rail at substantially right angles thereto, this arm having anopening, a clamping-bolt engaging such opening and one in the rail,ablock between the arm and the rail pierced with a perforation throughwhich the bolt also passes, and downturned flanges on the two oppositesides of the block standing astride the rail, as and for the purpose setforth.

3. In a spinning-machine, the combination with a series of spindles, anda ring-rail adjacent to and parallel with said series, the rail havingopenings opposite the spindles; of a ring for each spindle, an armsupporting each ring and resting upon the rail at substantially rightangles thereto, this arm having an opening, a clamping-bolt engagingsuch opening and one in the rail, a block between the arm and the railpierced with a perforation through which the bolt also passes, upturnedflanges on two opposite sides of the block standing astride the arm, anddownturned flanges on the remaining two opposite sides of the blockstanding astride the rail, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

AMARIAH AVERY.
